XETR and HXETR constitute a new generation of AES3 interface boards for NEXUS systems. For the first time, AES3 inputs and outputs are combined on one NEXUS card.


XETR can process four bidirectional AES3 signals, provides sample rate converters on all inputs and outputs, and comes with either XLR or BNC connectors. XETR can also operate as an input or output only card.

With 8 bidirectional AES3 signals, HXETR has twice the capacity of XETR. It is ideal for fixed installations and is supplied with either D-Sub 25 or RJ45 connectors.
